Abstract: A fuel injection pump, for use with a supercharged internal combustion engine, is provided with a full-load stop that is adjustable by means of a stepper motor in dependence upon operating parameters such as engine speed and manifold pressure. An electrical control device for the stepper motor is housed in a casing which is flange-mounted on the fuel injection pump and cooled by fuel. Electrical transducers for engine speed and manifold pressure are also mounted on the fuel injection pump.

Abstract: A fuel injection pump has a stepped piston operatively disposed in a stepped bore so as to define a first pump work chamber and a second pump work chamber. A constant fuel injection quantity (h.sub.FE) is pumped to the second work chamber per pump piston stroke, and a variable fuel injection quantity is pumped out of the first pump work chamber to a common distributor groove which actuates delivery of the fuel to individual injection lines.

Abstract: A fuel injection pump of the distributor type which has a reciprocatingly driven pump piston that is load-bearing in a rotating distributor shaft which pumps fuel out of a pump work chamber to various fuel injection valves via a distributor opening. To control the duration of high-pressure injection, an electrically actuated valve is provided with a valve member in a valve chamber that communicates with the pump work chamber and from a second valve chamber, communicates with a low-pressure region. To terminate the high-pressure injection, the valve member makes a communication between the two valve chambers, whereupon the outflow of the fuel stream is controlled by disposing a diameter constriction in the connecting line, thus reducing any tendency to cavitation.

Abstract: A fuel injection pump for internal combustion engines which has an integrated feed pump with an outer ring and an inner ring, the latter being coupled to a drive shaft of the fuel injection pump via a toothing. The individual teeth of this toothing extend with their respective end face and tooth bottom along a respective circular arc about a center point, which is located in the radial plane of the drive shaft extending through these teeth along the axis of the drive shaft. As a result, an increased angular offset between the drive shaft and the plane of the inner ring without the risk of wear is possible.

Abstract: A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

Abstract: A distributor-type fuel injection pump is provided with a hydraulic injection adjusting mechanism whose injection adjusting piston adjusts the cam gear unit for driving the pump plunger to execute strokes corresponding to the desired position of the start of injection. The injection adjusting piston defines a control space on one side and a spring space receiving a return spring on the other side. The control space is connected via a throttle bore with the pump interior space which is filled with fuel by a delivery pump. The fuel pressure is adjusted by a pressure control valve. To prevent unstable pressure vibrations on the injection adjusting piston, which leads to defects in the operation of the fuel injection pump, the spring space is connected on one side with the suction side of the delivery pump via a first throttle and on the other side with the pressure side of the delivery pump via a second throttle having a smaller throttle cross section.

Abstract: A magnet valve that serves to block off a fuel intake line to control fuel flow to supply a pump work chamber of a fuel injection pump with fuel, a closing element has a bore entering at the face end, which bore can be closed by a valve member under the influence of a closing spring. When pressure surges occur in one part of the intake line which is closed by the closing element and leading to the pump work chamber, instead of the closing element and the entire cross section of the intake line portion being opened, only the cross section of the bore is opened. Once it has been pushed open, this bore is rapidly closed again by the low-mass valve member, so that only small quantities of fuel can flow via the bore for pressure equalization.

Abstract: The device for testing the nozzles of injection pumps includes a temperature-responsive element arranged in the return-flow conduit of the injection pump and connected to the input of a control device the output of which controls two solenoid-operated 4/2 directional control valves which alternately open or close the feeding port to the intake conduit of the pump under test. The test liquid which is alternately delivered into the intake conduit by means of two delivery pumps from two containers storing the test liquid at different temperatures. When the temperature of the test liquid discharged by the overflow valve in the injection pump exceeds an upper limit (for example 55.degree. C.), the control valve through which the warmer test liquid is supplied is closed and the other valve delivers the cooler test liquid into the injection pump. Similarly, when the temperature of the overflow drops below the limit value, the delivery of the test liquid is switched over to take place from the warmer container. In this manner it is possible to keep the temperature of the test fluid in the injection pump constant and the reproducibility of the injection test is considerably improved.

Abstract: To provide a surface of wear-resistant material on the start lever of a lever assembly for a fuel injection pump control apparatus, a headed bolt of hardened, wear-resistant material is punch-pressed into a plate-like portion of the lever being engaged by a positioning element so that continuous movement of the positioning element with respect to the lever will not wear out the engagement surface and thus change a preset position of the positioning element with respect to the engagement surface of the lever, while permitting the lever to be made of a material suited for its purpose without regard to the particular surface characteristics of the engagement surface with the positioning element.
